Txhua square nyob rau lub sij hawm lub sij hawm muab yam tsawg kawg nkaus lub npe ntawm lub keeb , nws cov cim, atomic naj npawb thiab txheeb ze atomic mass (atomic hnyav).
Hais txog qhov no, dab tsi yog pom nyob rau hauv qab ntawm lub ntsiab square ntawm lub periodic rooj?
Hauv txhua qhov element square , cov ntaub ntawv ntawm lub ntsiab cim, atomic naj npawb, atomic mass, electronegativity, electron configuration, thiab valence tooj yuav ua tau pom . Nyob ntawm hauv qab ntawm daim ntawv qhia hnub yog ob kab thaiv ntawm cov ntsiab lus uas muaj cov lanthanoids thiab actinides.
Tsis tas li ntawd, dab tsi suav nrog hauv lub thawv rau txhua qhov khoom? Lub thawv uas muaj txhua lub ntsiab lus yog lub npe hu ua lub ntsiab lus tseem ceeb. Txhua tus yuam sij muaj lub npe lub npe, cim cim, qhov hnyav atomic thiab tus lej atomic.
Piv txwv li, dab tsi yog lub sij hawm periodic table?
Cov daim ntawv qhia hnub , kuj hu ua daim ntawv qhia hnub ntawm cov ntsiab lus, yog ib tug tabular zaub ntawm cov ntsiab lus tshuaj, uas yog teem los ntawm atomic tooj, electron configuration, thiab rov tshwm sim chemical zog. Cov kab, hu ua pawg, muaj cov ntsiab lus nrog cov cwj pwm zoo sib xws.
Dab tsi yog atomic mass number?
Cov pawg naj npawb (Symbol A, los ntawm German lo lus Atomgewicht [ atomic luj]), kuj hu ua atomic loj naj npawb los yog nucleon tus lej , yog tag nrho tus lej ntawm protons thiab neutrons (ua ke hu ua nucleons) hauv ib atomic nucleus. Cov pawg naj npawb Nws txawv rau txhua qhov sib txawv ntawm cov isotope ntawm cov khoom siv tshuaj.

Lub ntsiab lus ntawm chi square faib yog dab tsi?
Kev faib tawm Chi Square yog qhov faib ntawm cov lej ntawm squared tus qauv ib txwm sib txawv. Cov qib ntawm kev ywj pheej ntawm kev faib khoom yog sib npaug rau tus naj npawb ntawm cov txheej txheem ib txwm deviates raug summed. Lub ntsiab lus ntawm Chi Square faib yog nws qib kev ywj pheej
Dab tsi yog lub ntsiab lus ntawm kev hloov pauv lom neeg hauv cov ntsiab lus ntawm allele zaus?
Microevolution, los yog evolution ntawm ib tug me me, yog txhais raws li ib tug kev hloov nyob rau hauv lub zaus ntawm noob variants, alleles, nyob rau hauv ib tug pej xeem ntau tiam. Lub teb ntawm biology uas kawm txog allele frequencies nyob rau hauv cov pejxeem thiab yuav ua li cas lawv hloov lub sij hawm yog hu ua pej xeem noob caj noob ces
